Abstract (en)

[origin: WO9636758A2] The present invention relates to articles comprising a porous web that has been treated with a curable, shear thinnable, thixotropic material and with one or more modifiers. The modifiers are controllably and selectively positioned within the web leaving at least some of the porous web open. The modifiers are localized or concentrated at one or more selected positions within the web. A variety of modifiers, or combination of modifiers, can be used to alter the functional properties of the article. The invention also relates to methods for making the foregoing articles which include applying a curable, shear thinnable, thixotropic material to a porous web; applying one or more modifiers to the porous web; and subjecting the thixotropic material and modifiers to sufficient energy to cause the thioxotropic material and modifiers to flow into the porous web and selectively position the modifiers within the web, leaving at least some of the intersticial spaces of the web open.
